I know I've asked a similar question before, but it's been a while, and I'd
prefer a new thread that I can browse to quickly.

When attaching text to a path (such as a spline or other function) is whitespace
taken into account? E.g., are the proper whitespace rules followed, so that the
transition from one character to the next is the same as it normally is?

Your post shows inside the old thread, which made it appear almost at 
the top of the thread list. Thunderbird orders by the date the thread 
was created, not by the most recent post. Better try again, or a lot of 
people will miss your message :)

Apears treaded corectly here, using Thunderbird. Set to view by tread, new at 
the end.

Thunderbird will also show a new thread as a reply to an older one if
the titles are the same and strict threading is not turned on. It can be
fixed, though.

This thread appears correct to me with those settings.

If you are using Spline_Trans to place letters then the spacing
is up to you...
In some spline with a time index, the distance between points
at regular time intervals is not required to be spaced evenly.

Here's a macro to determine the length of a portion of a spline...

// calculate the length of a spline
#macro Len_Spline(Espl begin_at stop_at num)
   #local c = 1/num;
   #local V1 = Espl(begin_at);
   #local result = 0;
   #while (c <= 1)
      #local V2 = Espl( c*(stop_at - begin_at) + begin_at);
      #local result = result + vlength(V2-V1);
      #local V1 = V2;
      #local c = c + 1/num;
   #end
   (result)
#end

Ah, so it's not automatic. I was hoping it was. In SVG, for instance, you can
wrap text along a spline, and the proper positioning of each character is
retained.
